Sandisk
Sandisk's revenue rose 175.3% to $20.2 billion in fiscal 2026. Its operating margin was 61.2%, up from −18.7% a year earlier. Free cash flow was $11.5 billion. It paid out $4.5 billion in dividends and buybacks, 39% of free cash flow. The diluted share count rose 6.9%.
Operating margin is operating income as a share of revenue. Free cash flow is cash from operations minus capital spending. Return on capital is after-tax operating income as a share of the money invested in the business: debt plus equity, minus cash. Market cap is the last closing share price times the latest diluted share count, so it is approximate. P/E is the last close divided by diluted earnings per share over the last four quarters, or the latest fiscal year where the quarters aren't available; there is none when the company made a loss.
What Sandisk does
Sandisk makes flash memory, the kind of chip that keeps data stored when the power is off. It designs the chips and the products built from them, and it makes them itself. Its products include solid-state drives (SSDs), memory built into devices, removable memory cards, USB flash drives, and wafers and components. It has more than 30 years of experience with NAND flash, the most common type. Until February 21, 2025 it was wholly owned by Western Digital, and it has been a separate public company since then.
Sandisk sells into three end markets. Datacenter covers products for cloud providers, private clouds and business servers, including drives for artificial intelligence work. Edge covers products it sells to computer, phone, gaming and car makers and through channel partners, who build them into devices. Consumer covers retail products such as portable drives, memory cards and USB drives sold under its own brand. For a limited time, some products are also sold under the Western Digital and WD names under a license.
The company says its industry is highly competitive, with falling average selling prices, volatile demand and rapid technology change. It relies on partners, including Kioxia, and holds about 8,000 granted patents and about 3,000 pending patent applications worldwide.
Its biggest risks, as it describes them
- Falling prices, swings in demand and fast technology change in the flash memory industry.
- Reliance on a small number of qualified suppliers, and on partners such as Kioxia.
- Losing a key customer, or customers combining, since a few buy a large share of its products.
- Its guarantees of obligations of Flash Ventures, and the covenants in its credit facility.
- Product defects that lead to recalls, warranty claims or lawsuits.

Valuation
Two ways to value Sandisk yourself, both starting from its filings: a discounted cash flow model and the price-to-earnings method.
Discounted cash flow (DCF)
A discounted cash flow (DCF) model values a business as the cash it may generate in future, discounted back to today. The starting figures come from Sandisk's 10-K and the assumptions are yours: start from one of three example scenarios, then change any figure to see what it implies for a share, and how that compares with the last share price.
Value per share on three example scenarios, from Sandisk's fiscal 2026 free cash flow of $11.5B, net cash of $4.8B at July 3, 2026 and 155 million diluted shares, from its filings. The scenarios are fitted to Sandisk: the base scenario's growth in years 1 to 5 is its revenue growth over the last 3 years, 49.3% a year, kept between 0% and 20%; the cautious and optimistic ones are lower and higher, and growth in years 6 to 10 is halfway to the long-run rate. The base scenario's discount rate is 10%: 9% for a business of moderate risk (Technology Hardware, Storage & Peripherals), plus 1 point for unsteady results (a loss in fiscal 2025); the cautious and optimistic ones use a point more and a point less. Select one to load it into the calculator. These are the model's arithmetic on those assumptions, not a forecast or a price target.

How the value changes with two assumptions
Price-to-earnings (P/E) method
Another common way to value a company is to multiply its earnings per share by a price-to-earnings (P/E) multiple: the number of years of today's earnings an investor pays for a share. A higher multiple usually means investors expect earnings to grow. Choose a multiple, for example from similar companies, to see the value it gives.
Value per share on three example scenarios, from Sandisk's earnings per share of $73.76 (in fiscal 2026). Each grows earnings for a year at the cash flow scenarios' rates and applies a multiple to next year's earnings: 22.1×, the middle of Sandisk's own P/E today, its peers' median and its sector's median (its peers' median) for the base scenario, 20% less and more for the cautious and optimistic ones. The price is brought back a year at 11%, 10% and 9%. Select one to load it into the calculator. These are the model's arithmetic on those assumptions, not a forecast or a price target.
